This application provides a BIER packet sending method. The method includes: receiving a BIER packet that is encapsulated using an IPv6 protocol and that is sent by a second forwarding device, where the BIER packet includes an IPv6 basic header and a BIER header, a destination address field in the IPv6 basic header is a first IPv6 address of the first forwarding device; determining, based on an identifier corresponding to a first IPv6 address in a forwarding table, to perform BIER forwarding on the BIER packet, where the identifier is used to indicate that the first IPv6 address is a destination address for BIER forwarding. In the technical solution provided in this application, a node may determine, based on the identifier of the first IPv6 address, to perform BIER forwarding on the BIER packet.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The method according to claim 3, wherein the routing protocol comprises any one of the following protocols: an intermediate system to intermediate system (IS-IS) protocol, an open shortest path first (OSPF) protocol, or a border gateway protocol (BGP).
8. The method according to claim 1, wherein the IPv6 packet further comprises an extension header, and the extension header comprises the BIER information.
9. The method according to claim 8, wherein the extension header is a destination option header, a routing header (RH), or an authentication header (AH).
10. The method according to claim 1, wherein the first IPv6 address is a first segment identifier (SID).
11. The method according to claim 10, wherein a type of the first SID is End.BIER.
14. The method according to claim 1, wherein the first IPv6 address is a unicast address.
21. The apparatus according to claim 15, wherein the IPv6 packet further comprises an extension header, and the extension header comprises the BIER information.
22. The apparatus according to claim 21, wherein the extension header is a destination option header, a routing header (RH), or an authentication header (AH).
23. The apparatus according to claim 15, wherein the first IPv6 address is a first segment identifier (SID).
24. The apparatus according to claim 23, wherein a type of the first SID is End.BIER.
27. The apparatus according to claim 15, wherein the first IPv6 address is a unicast address.
29. The non-transitory computer-readable storage medium according to claim 28, wherein the first IPv6 address is a unicast address.
